How to use sscanf or similar functions in Energia? #921

Closed bcm0 closed 8 years ago

bcm0 commented 8 years ago

Hi there,

do you have a quick replacement for the sscanf function, that reads formatted data from a string? I didn't find a reasonable solution and want to use some Arduino code on a MSP430G2553.

Thanks for any help! Nokian

Have you tried #include stdio.h?

bcm0 commented 8 years ago

Thanks for your answer. I already tried that. I also compared the stdio.h files of the Arduino IDE and Energia. Energia misses some functions. I suppose there is no other way, than writing that function on my own for my specific use case.

This is not supported by the current msp430 gcc compiler. An updated compiler will be released in the next couple weeks that does support this feature. Please note that these functions take up a lot of RAM/FLASH and using them on a MSP430G2553 might result in code no longer fitting in RAM/FLASH

Is the compiler updated ? And how can I get it ?

robertinant commented 7 years ago

It has not yet been updated. There are some other fixes/features that are being added to the msp430 core before I can move to the new compiler.
